strong winds, typhoons or earthquakes.
Failure to do so during installation work may result in the unit falling and causing accidents.
Make sure that a separate power supply circuit is provided for this unit
•
and that all electrical work is carried out by qualified personnel according to local and national regulations and this installation manual.
An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire.
• Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor
or telephone earth lead. Imperfect earthing may result in
electric shocks or fire.
A high surge current from lightning or other sources may cause
damage to the air conditioner.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric
shocks or fire.
• Be sure to switch off the unit before touching any electrical parts.
• Make sure that all wiring is secured, the specified wires are used,
and that there is no strain on the terminal connections or wires.
Improper connections or securing of wires may result in abnormal
heat build-up or fire.
• When wiring the power supply and connecting the remote controller wiring and transmission wiring, position the wires so that the
EL. COMPO. BOX lid can be securely fastened.
Improper positioning of the EL. COMPO. BOX lid may result in

1 English
Caution
• While following the instructions in this installation manual,
install drain piping to ensure proper drainage and insulate piping to prevent condensation.
Improper drain piping may result in indoor water leakage and
property damage.
• Install the indoor, outdoor and function units, power cord and connecting wires at least 1 meter away from televisions or radios to
prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter
may not be sufficient to eliminate noise.)
• Remote controller (wireless kit) transmitting distance can be
shorter than expected in rooms with electronic fluorescent lamps
(inverter or rapid start types).
Install the indoor unit as far away from fluorescent lamps as possible.
• Make sure to provide for adequate measures in order to prevent
that the outdoor unit be used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the
area around the unit clean.
• Do not install the air conditioner in the following locations:
1. Where there is a high concentration of mineral oil spray or
vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and water leakage could result.
2. Where corrosive gas, such as sulphurous acid gas, is pro-
duced.
Corroding of copper pipes or soldered parts may result in
refrigerant leakage.
3. Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of the
control system and result in a malfunction of the unit.
4. Where flammable gas may leak, where there is carbon fibre or
ignitable dust suspensions in the air, or where volatile flammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
• The air conditioner is not intended for use in a potentially explosive atmosphere.
1-2 Special notice of product
[CLASSIFICATION]
This air conditioner comes under the term “appliances not accessible
to the general public”.
[EMC CHARACTERISTICS]
This system is a class A product. In a domestic environment this
product may cause radio interference in which case the user may be
required to take adequate measures.
[REFRIGERANT]
This system use R410A refrigerant.
• The refrigerant R410A requires that strict precautions be
observed for keeping the system clean, dry and tightly sealed.
Read the chapter “REFRIGERANT PIPING” carefully and follow
these procedures correctly.
A. Clean and dry
Strict measures must be taken to keep impurities (including
SUNISO oil and other mineral oils as well as moisture) out of
the system.
B. Tightly sealed
Take care to keep the system tight when installing.
R410A contains no chlorine, does not destroy the ozone layer
and so does not reduce the earth’s protection against harmful
ultraviolet radiation. R410A will contribute only slightly to the
greenhouse effect if released into the atmosphere.
• Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state. (If the system is charged
with refrigerant in its gaseous state, due to composition change,
the system will not function normally.)
Limit by the total maximum refrigerant charge
The total maximum refrigerant charge of a VRV system must be
below 100kg, this to be in accordance with CE requirement
(EN60335-2-40 standard).
This means that in case the total maximum refrigerant charge of the
system (factory and additional charge) is equal to or more than
100kg you must divide your multiple outdoor system into smaller
independent systems, each containing less than 100kg refrigerant
charge.
For factory charge, refer to the unit name plate.

3. SELECTION OF LOCATION
Select a location for installation that meets the following conditions
and get the customer’s permission.
There is no danger of fire due to leakage of inflammable gas.
(1)
Select the location of the unit in such a way that neither the dis-
(2)
charged air nor the sound generated by the unit disturb anyone.
The foundation is strong enough to support the weight of the unit
(3)
and the floor is flat to prevent vibration and noise generation.
The piping length between the outdoor unit and the indoor unit
(4)
may not exceed the allowable piping length.
(Refer to “6. REFRIGERANT PIPING”)
Locations where the unit’s suction vent and outlet vent do not
(5)
generally face the wind.
Wind blowing directly into the suction or outlet vents will interfere
with the unit’s operation.
If necessary, install some kind of obstruction to block the wind.
The space around the unit is adequate for servicing and the min-
(6)
imum space for air inlet and air outlet is available.
(See the “Installation Space Examples” for the minimum space
requirements.)
Installation Space Examples
• The installation space requirement shown in figure 2 is a refer-
ence for cooling operation when the outdoor temperature is 35°C.
If the design outdoor temperature exceeds 35°C or the heat load
exceeds maximum capacity in all the outdoor unit, take an even
large space on the intake shown in figure 2.
• During installation, install the units using the most appropriate of
the patterns shown in figure 2 for the location in question, taking
into consideration human traffic and wind.
If the number of units installed is more than that shown in the pattern in figure 2, install the units so there are no short circuits.
• As regards space in front of the unit, consider the space needed
for the local refrigerant piping when installing the units.
• If a snowbreak hood (sold separately) is mounted, secure the
required space of installation including the outer dimensions of
the product and snowbreak hood.
• If the work conditions in figure 2 do not apply, contact your dealer
or Daikin directly.

For Patterns 1 and 2 in figure 2 :
• Wall height for front side – no higher than 1500 mm.
• Wall height on the suction side – no higher than 500 mm.
• Wall height for sides – no limit.
If the height is exceeded the above, calculate h1 and h2 shown in
the figure below, and add h2/2 to the service space of front side
and h1/2 to the service space of suction side.

Note
An inverter air conditioner may cause electronic noise gener-
(1)
ated from AM broadcasting. Examine where to install the
main air conditioner and electric wires, keeping proper distances away from stereo equipment, personal computers, etc.
Particularly for locations with weak reception, ensure there is
a distance of at least 3 meters for indoor remote controllers,
place power wiring and transmission wiring in conduits, and
ground the conduits.

When installing in a locations where there is heavy snowfall,
(2)
implement the following snow measures.
• Install the outdoor unit and function unit on a mount (procured locally) so that they may not be buried or covered
with snowfall while the bottom frame will be 200 to 300 mm
higher than the surface of the deposited snow.
• Mount the snowbreak hood (sold separately) and dismount
the rear suction grille (see fig. 3).
When mounting the snowbreak hood (sold separately) to
(3)
the air inlet, make sure that the air outlet of the snow protection food will be located right angles to the winter wind or in
the leeward direction.
If the outdoor temperature of the place of installation is low
(4)
in winter and defrost water discharged from the system
freezes while the system is in defrost operation in heating
mode, provide a sufficient space between the bottom frame
of the outdoor unit and the foundation side. (A space of 500
to 1000 mm is recommended.)
If condensate may drip on downstairs (or walkway) depend-
(5)
ing on the floor condition, take a measure such as the installation of drain pan (field supply).
The refrigerant R410A itself is nontoxic, nonflammable and is
(6)
safe. If the refrigerant should leak however, its concentration
may exceed the allowable limit depending on room size. Due to
this it could be necessary to take measures against leakage.
See “12. CAUTION FOR REFRIGERANT LEAKS” for details.
4. INSPECTING AND HANDLING THE UNIT
• At delivery, the package should be checked and any damage
should be reported immediately to the carrier claims agent.
• When handling the unit, take into account the following:
(1)
(2)
(3)
Note
(4)
Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
Decide on the transportation route.
If hanging the unit, keep the following points in mind and hang the
unit following the procedure shown in figure 4.
• Use a sling sufficiently strong to hold the mass of the unit.
• Use 2 sling of at least 8m long.
• Place extra cloth or boards in the locations where the casing
comes in contact with the sling to prevent damage.
•
Hoist the unit making sure it is being lifted at its center of gravity.
In the case of transporting the outdoor unit by forklift, insert the
fork into the opening (large) under the bottom of the outdoor unit.
(Refer to figure 5)
The function unit is not provided with any opening for fork insertion.
• Apply a filler cloth on a fork to prevent coating of the bottom frame
from coming off and rust from occurring when bringing the unit
using a forklift.
After the outdoor unit is installed, remove the transportation
bracket (yellow) by pushing the hook mounted to the opening
(large) of the outdoor unit. (Refer to figure 5)
